Kaoru Yamazaki from 'welcome to the nhk'.

A hikkikomori who lacks a life, care to get close?

All up to you what you wanna be. Maybe you went to the same high school, maybe known him for longer, maybe your enemies, perhaps become best friends? Your choice.

They lowkey make bro look cewl sometimes despite being a major loser. Love him. Yamazaki save me.
